Grade 8 · Algebra & Functions
Integer Exponents
Learn to reason with repeated multiplication and exponential scale through clear explanations, worked examples, an interactive model, and guided practice.
Lesson coverage
Learn the whole topic, not just one problem type.
This lesson and its practice bank deliberately rotate across these core facets so students build a connected understanding of the subject.
Interpret powers as repeated multiplication.
Compute powers and scientific notation values.
Use product, quotient, and power relationships when appropriate.
Reason about exponential size and order of magnitude.
Use exponential relationships in models and scientific notation.
Build the idea
Integer Exponents is part of the prepare for high-school algebra with real numbers, linear relationships, functions, transformations, geometry, and bivariate data. Start by identifying what each quantity, symbol, diagram, or graph represents before calculating.
Meaning
Interpret powers as repeated multiplication. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Evaluate
Compute powers and scientific notation values. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Exponent rules
Use product, quotient, and power relationships when appropriate. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Compare scale
Reason about exponential size and order of magnitude. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Applications
Use exponential relationships in models and scientific notation. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Use a reliable strategy
Translate the information into symbols, apply one valid transformation at a time, and check the result in the original relationship.
Check and explain
A correct answer is only part of mathematical understanding. Check units, signs, scale, and whether the result makes sense. Then explain the relationship in words so you can recognize the same structure when the numbers or context change.

Repeated multiplication gives 27.
When multiplying powers with the same base, add exponents: 2 + 3 = 5.
Guided practice
20 questions drawn from a 150-question lesson bank.
